Application filed October 18, 1917. Serial No. 197,326.

To all whom it may concern:

Be it knownthat I, JOHN P. ATKINSON, a citizen of the United States,residing at Houston, in the county of Harris, State of Texas, haveinvented certain new and useful Improvements in. Attachments forInternal-Combustion-Engine Carbureters, of which the following is aspecification.

The present invention relates to an attachment for internal combustionengine sists in providing a sleeve, one end of which is split andadapted for application to the air intake of the carbureter, the sleevebeing constructed with a stationary diifusingdisk comprising a pluralityof vanes past which the air passes in entering the air intake of thecarbureter.

A further feature of the invention consists in producing a device of thecharacter described which is of simple and cheap construction andparticularly one which may be readily applied to the air intake of thecarbureter without the use of tools or changing the construction of thecarbureter and its associated parts.

Further features will be apparent upon reference to the accompanyingdrawing and the following detailed description.

In the drawings 2- Figure 1 is a side elevation of a conventional typeof carbureter showing the attachment as applied thereto;

Fig. 2, is a sectional view of the attachment; I

Fig. 3 is a side elevation of the attachment; and

Fig. 4 is a sectional view on the line 4-4 of Fig. 2.

A represents a conventional type of carbureter having the usual fuelconnection B, an air intake C and a manifold connection D. Theattachment preferably comprises a sleeve 5 formed of thin sheet metal ofany appropriate length having a split end 6 adapted to-be inserted inthe air intake C of the carburetor. An abutment 7 comprising an annularring on the sleeve intermediate its ends bears against the open end ofthe. air intake and prevents the split end of the sleeve from beinginserted too far into the intake. Provided in the sleeve 5 is astationary diffusing disk 8 which is constructed with a plurality ofvanes struck from a common center with the surface of each vane disposedat an angle to the axis of the sleeve. This disk is produced separatefromthe sleeve but with a diameter of substantially that of thesleeve-in order that it may have a tight fit in the sleeve and beretained in place; some of the wanes, however, may be soldered to thesleeve to revent displacement of the disk. In practice the disk impartsa whirling or spiral motion to the air entering the air intake of thecarbureter and greatly. improves. the explosive mixture entering thecylinders of the engine. 1; I

The attachment proposed by the present invention may be easily andcheaply manufactured and sold in the open market as an accessory. Anyonemay purchase the same at a comparatively low. cost and apply it to thecarbureter of an engine without the use of tools or even the assistanceof a mechanic. For commercial advantages the device may be made indifferent sizes corresponding to the different sized carbureters.

I claim.- 1

An. attachment for internal combustion engine carbureters comprising asleeve one end of which is. split and adapted for application to the airintake of a carbureter, an abutment on the sleeve adapted to bearagainst the open end of the air intake, and

a stationary diffusing disk in said sleeve adapted to impart a whirlingmotion to air :entering the air intake, said disk comprising a pluralityof vanes struck from a common center with the-surface of each vane at anangle to the aXiS of the sleeve.

The foregoing specification signed at Houston, Texas, his fifteenth dayof October, 1917.
